Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142080, here are decompositions:
- 13 + 142067 = 142080
- 19 + 142061 = 142080
- 23 + 142057 = 142080
- 31 + 142049 = 142080
- 41 + 142039 = 142080
- 61 + 142019 = 142080
- 73 + 142007 = 142080
- 89 + 141991 = 142080
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 142,080 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 142080 first appears in π at position 12,895 of the decimal expansion (the 12,895ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
